I was trying to reply this post, but then...I myself become really confused.
I first wrote "redo works with all 'iterators', like for, while, do", then I started to coding and test, however I was stuck with this piece of code:
use strict;
my $i = 1;
my $flag = 1;
do {
print "$i ";
if (($i ++ == 5) && $flag) {
$flag = !$flag;
#redo;
}
} until ($i >= 10);
If I uncomment that redo, perl gave me "can't redo outside a loop block". (Perl was fine with for and while)
Did I miss something obvious, or that is just the way perl goes, (if that is the way perl goes, I don't buy their logic at all, "do {} unitl" is not a loop?)
